Thanks for requesting updates on the Standard Bank connection issue in QuickBooks Online.
Right now, our engineers found that the reason for this issue is due to a back-end change made by the bank.
We are working with the bank to have the issue resolved as quickly as possible. However, we don't currently have time for resolution, as the issue relies entirely on the Banks, but as soon as we do, we will send a further update. With this said, I suggest contacting our Customer Care Team, so you'll be added to the list of affected users.
We appreciate your ongoing patience while we continue to work on resolving this issue. If you have additional questions or concern, leave me a comment below. I'll get back to you as soon as I can. Take care.
